Definitions

  • the invention relates to a lock.
  • the lock is designed in particular for installation in a door leaf. It is particularly preferably a panic lock.
  • the locks considered here have in particular a lock case and a faceplate and are designed for installation in a door leaf.
  • a door handle is usually connected via a nut of the lock.
  • the latch of the lock can be withdrawn by operating the door handle.
  • previously known locks can be designed to accommodate a cylinder lock with a driver. By turning the driver, a bolt of the lock is locked and retracted.
  • a mechanism is provided within the lock that enables the bolt to be drawn in by turning the nut (using the door handle).
  • a panic lever is provided within the lock, for example, which converts the rotary movement of the nut into a translational movement of the bolt.
  • a change mechanism within the lock.
  • This interchangeable mechanism allows the latch to be withdrawn by turning the driver.
  • a change element also: lower change
  • the change element in turn actuates an upper change or the nut via a nut arm in order to pull back the latch.
  • panic actuation can result in the interchangeable element guided on the bolt shank blocking the driver. In this way, complete retraction of the bolt can be blocked in the event of a panic.
  • EP 0 795 664 A2 shows a mortise lock in which the bolt return takes place by pre-tensioning a slide, which is held in a trap by means of a locking lever during the bolt return so that a sudden bolt locking occurs after the lock is released.
  • the mortise lock is designed in particular as a tubular frame lock.
  • DE 299 10 758 U1 shows a lock in which the change is guided on a predetermined path in such a way that a translatory-rotary movement occurs when the lock bit is turned, which represents a geared coupling between the pure rotary movement of the lock bit and the pure translational movement of the latch across the mortise lock.
  • a displacement element is provided which, when the handle follower is actuated, moves into the return path of the return path lock on the change. This prevents the return path lock from returning, ie the switch cannot return to its basic position. This also keeps the trap in its retracted position as long as the return path of the reverse path lock remains closed.
  • the lock is designed in particular as a mortise lock. Furthermore, the lock is designed in particular as a panic lock.
  • the lock preferably comprises a lock case.
  • the lock includes a trap.
  • the trap comprises a trap head connected to a trap shaft.
  • the latch shaft is guided in a linearly movable manner inside the lock, in particular in the lock case.
  • the lock also includes a bolt.
  • the bolt can be moved along a bolt axis to lock the lock.
  • the bolt comprises a bolt head which is firmly connected to a bolt shaft.
  • the bolt shaft is guided in the lock case so that it can move linearly along the bolt axis. This allows the bolt to lock the door to be locked out and retracted to unlock the door.
  • the lock comprises a rotatable driver or is designed to receive a rotatable driver.
  • This rotatable driver is in particular stored in the lock case or part of a cylinder lock.
  • a cylinder lock receptacle is also particularly preferably provided.
  • This cylinder lock holder is used to hold a cylinder lock in the lock case.
  • the cylinder lock is in particular connected or connectable to an in particular electromechanical knob.
  • the axis of rotation of the driver is in particular perpendicular to the bolt axis.
  • the driver does not necessarily have to be operated with a key; but can also be turned in some other way, in particular by means of a knob. In normal operation of the lock, the bolt is locked and retracted by turning the driver. This movement can be single-turn or multi-turn.
  • the cylinder lock can be used in the lock or can be inserted into the lock.
  • the lock can thus include the cylinder lock or be connectable to the cylinder lock.
  • the lock particularly preferably also comprises a tumbler.
  • This tumbler is actuated by the driver, preferably raised, whereby a blocking of the bolt is canceled.
  • the lock also includes an end stop.
  • the end stop is in particular "bolt-proof". This means that the end stop is part of the bolt or is arranged on the bolt and does not move relatively, but rather together with the bolt.
  • the lock also includes an interchangeable element.
  • the change element can be actuated by the driver.
  • the rotating driver can move the interchangeable element linearly, in particular lift it.
  • the interchangeable element is designed to retract the trap.
  • the interchangeable element is arranged to be rotatable about an alternate rotation axis perpendicular to the bolt axis. This alternating axis of rotation basically enables the interchangeable element to rotate in two directions. In one direction of rotation, the interchangeable element rests against the end stop described. In the opposite direction of rotation, the interchangeable element can be rotated against the force of an interchangeable spring.
  • the interchangeable spring enables the interchangeable element to be rotated or pivoted. This is especially true in the following process of Advantage: As described, the end stop is locked to the bolt, which means that the interchangeable element is forcibly guided by the bolt. If the driver is now in an unfavorable position, for example at three o'clock or nine o'clock, and the bolt is not drawn in by turning the driver, but in some other way (for example via the panic function), the interchangeable element strikes the driver. As a result, the bolt retraction would be blocked without the alternate spring described.
  • the interchangeable spring provided here, however, enables the interchangeable element to evade. During this evasive action, the interchangeable element is rotated against the force of the interchangeable spring.
  • An unfavorable position of the driver can result in particular if the driver can be rotated by a knob, in particular an electromechanical knob.
  • the interchangeable spring is supported on the interchangeable element and on the bolt.
  • the interchangeable spring is therefore not attached to or supported on the lock case, but moves together with the interchangeable element and the bolt.
  • the exchangeable spring is fastened to the exchangeable element and rests against the end stop which is fixed to the bolt.
  • the interchangeable spring is designed as a leaf spring.
  • the interchangeable element has a recess.
  • the end stop protrudes into this recess.
  • the exchangeable spring is arranged in this recess.
  • the end stop is preferably located between a wall of the recess and the alternating spring, in particular designed as a leaf spring. In one direction of rotation, the wall of the recess strikes the end stop. In the opposite direction of rotation, movement is possible to a certain extent, since the end stop rests against the exchange spring and deforms it elastically.
  • the position of the alternating axis of rotation is preferably above the bolt.
  • the position "above the bolt” is defined by the usual installation position of the lock. Alternatively, it can also be defined that the alternating rotation axis is located on the side of the bolt facing the latch.
  • the interchangeable element is guided in a linearly displaceable manner on the interchangeable axis of rotation via a link guide.
  • the alternating axis of rotation is formed by an extension fixed to the lock case.
  • This extension protrudes into a corresponding groove of the interchangeable element, which results in the link guide.
  • This link guide enables both the linear displaceability and the rotatability of the interchangeable element.
  • the linear displaceability is provided in particular for the regular function of the interchangeable element.
  • the change element is lifted linearly by turning the driver and actuates an upper change or a nut arm.
  • the interchangeable element described here is preferably a rigid component.
  • the interchangeable element is constructed in one piece.
  • the interchangeable element can also be composed of several components. It is crucial, however, that the interchangeable element is preferably a rigid component and therefore cannot be moved relative to one another Components is composed. Any other mechanism that is necessary to actuate the latch, for example the upper changeover or actuation via a nut arm, is preferably provided in addition to the changeover element described and is preferably located above the bolt.
  • the interchangeable element is arranged for direct actuation of a follower arm of the lock.
  • the interchangeable element thus touches and actuates a nut arm directly without intermediate elements.
  • the nut is rotated by operating the nut arm.
  • the trap can be withdrawn in a conventional manner.
  • the lock preferably comprises a panic lever.
  • the panic lever can be operated by a nut arm and is arranged to retract the bolt.
  • the panic lever is rotatably attached in the lock case.
  • the lock comprises a tumbler lever.
  • the guard locking lever can also be actuated by a nut arm. This can in particular be the same nut arm that actuates the panic lever.
  • the tumbler lever is provided for releasing, in particular for lifting, the tumbler.
  • the guard locking can block the bolt.
  • the tumbler can be moved, in particular, between a release position in which the tumbler allows the bolt to move into the retracted position, and a locking position in which the tumbler blocks the bolt.
  • the guard locking is lifted by the rotating driver during normal operation of the lock.
  • the guard locking can be raised using the guard locking lever operated by the follower.
  • the tumbler can comprise an actuating surface for moving the driver.
  • the guard locking device moves from the release position into the blocking position, the guard locking device can move the driver.
  • a movement of the tumbler from the release position into the locked position of the driver is moved by the tumbler in the direction of the interchangeable element.
  • the bolt comprises a sliding surface, the sliding surface serving to move the driver when the bolt is moved.
  • the sliding surface serves to move the driver into its retracted position when the bolt is moved.
  • the sliding surface can preferably move the driver in the direction of the interchangeable element.
  • the sliding surface can in particular serve to move the driver out of engagement with the bolt. A dead center can be avoided by the sliding surface.
  • the sliding surface can move the bolt in such a way that the driver does not subsequently hit the bolt in the direction of the movement axis of the bolt during the movement of the bolt into the retracted position.
  • the actuating surface and the sliding surface are particularly preferably coordinated with one another. It can thus be the case that the actuating surface is designed to initially move the driver in such a way that the driver can then be moved through the sliding surface.
  • the bolt can, for example via the panic function, independently of a rotary movement of the driver to be withdrawn.
  • the interchangeable element can hit the driver and be twisted against the force of the alternating spring.
  • This rotation of the interchangeable element and the restoring force of the interchangeable spring results in a force on the bolt in the locking direction via the end stop.
  • This force acting on the bolt in the direction of exclusion is undesirable, especially in the event of panic.
  • an elastic latching arrangement is preferably provided in the lock.
  • the latching arrangement is designed to hold the bolt in its retracted position.
  • the latching arrangement is designed and arranged to hold the bolt in its retracted end position.
  • the bolt only engages in the locking arrangement when it is reached or shortly before reaching its retracted end position.

  • the latching surface and the actuating surface are two surfaces of the bolt shaft which are angled to one another, preferably at an acute angle.
  • the elastic latching arrangement and the interchangeable spring are designed in such a way that the maximum force acting on the latch due to the interchangeable spring is not sufficient in the locking direction to release the latching arrangement.
  • the latching arrangement should not be released until the bolt is moved again in the locking direction, for example by rotating the driver.
